inheritance of resistance to powdery mildew (erysiphe graminis f. sp. hordei) in barley
two barley (hordeun vulgare l.) genotypes, radical and cwb, with good to moderate levels of resistance to powdery mildew were crossed with a highly susceptible cultivar (afzal) to determine the genetics of resistance. the parents, fl, f2 and f3 generations of each of the two crosses, were evaluated for powdery mildew resistance in the glasshouse and field at the college of agriculture in karaj ...
متن کاملAccumulation of potentiometric and other dyes in haustoria of Erysiphe graminis in living host cells
Twenty-five vital fluorescent dyes were tested for accumulation in haustoria of Erysiphe graminis (DC) Merat f. sp. hordei Em . Marchai when applied to coleoptile epidermal host cells of Hordeum vulgare L . Eight of the dyes gave fluorescence to structures judged to be haustorial mitochondria . The potentiometric cyanine dyes, DiOC4 (3) and DiOC 7 (3) gave best differentiation between the putat...
متن کاملComposition of guttation fluid from rye, wheat, and barley seedlings.
This work was undertaken to determine the kinds and amount of substances that would account for the previously demonstrated differential growth of Claviceps purpurea on guttation fluids from Rosen rye, Genesee wheat, and Traill barley seedlings. Chromatographic methods were used for determining amino acids and sugars, spot tests and spectrometric methods for inorganic materials, and microbiolog...

increases over controls were found when root segments were incubated in phosphorus solutions containing 10-3 A D)NP ancd at lowx temlperatture. The increased Pi in Al-roots did niot result in an increase in the total amounit of l)hosphorus incorporated into phosphorylated compounds. Aluminum treatnment miiarkedly decreased the incorporation of P32 into sigar phosl)hates but increased the pool s...
متن کاملCatalase-chlorophyll Relationship in Barley Seedlings.
For over two decades H. VON EULER (3) and his coworkers have studied the relationship of catalase to chlorophyll. In their work they utilized various chlorophyll defective plants including genetic albinos, variegated, chlorotic and etiolated plants. In general, they found a parallelism between chlorophyll content and catalase activity. NAKAMURA (11) working with a number of higher and lower for...
